3.4 ANSI Programming

The AccuTerm ANSI emulations provide VT52, VT100, VT220, VT320, VT420, SCO Console, Linux

Console and ANSI BBS emulations. The VT220, VT320 and VT420 emulations support international characters, 7 and 8 bit control codes, programmable function keys and a robust command set. VT100 supports 7 bit control codes and a subset of the VT220 command set.

The SCO Console emulation uses the PC (OEM) character set and supports programmable function keys and text and background colors.

The Linux Console emulation uses the ANSI character set, and includes support for programmable function keys, text and background colors, and mouse.

The ANSI BBS emulation supports the PC (OEM) character set and the attribute and cursor commands supported by the DOS ANSI.SYS device driver (AccuTerm does not use the ANSI.SYS driver). The

ANSI BBS emulation only supports 7 bit escape sequences.

When AccuTerm is emulating a VT220, VT320 or VT420 terminal snipor SCO or Linux Console, it will respond to 7-bit and 8-bit control codes (hex 00-1F and 80-9F). For convenience, command sequences which may use 8-bit control codes are documented using the 8-bit control code. For every 8-bit control code, an equivalent 7-bit escape sequence may also be used, as shown in the following table:

AccuTerm 7 Reference 241

This chapter documents commands used by all of the ANSI emulations supported by AccuTerm. Not every command is valid for all ANSI emulations. Those commands which are only valid for certain emulations are shown with a reference note after the command definition. These reference are indicated by a superscript, and are VT100 1 , VT220 2 , VT320 3 , VT420 4 , ANSI BBS A , Linux Console L , and

SCO Console S .

The AccuTerm ANSI emulations operate in a variety of modes. Some of the default operating modes are determined by settings in the AccuTerm configuration. Most of these modes can be changed by commands received from the host. Operating modes which can be selected in the Settings dialog and saved in a configuration file are:

VT52, VT100, VT220, VT320, VT420, SCO Console, Linux Console or ANSI BBS emulation

80 (normal) or 132 (extended) columns

Automatic wrap at end of line

Send 7 or 8 bit control codes

Numeric keypad sends “application” codes instead of numbers

Cursor keys send “application” codes instead of cursor codes

Backspace key sends

DEL

control code instead of

control code

The following operating modes are not determined by settings in the AccuTerm configuration, but may be changed by sending the appropriate ANSI command sequence:

Keyboard: default is unlocked.

Insert/Replace: default is replace.

Line feed / New line: default is line feed.

Origin: default is absolute.

Tabs: default is every 8 columns.

Cursor: default is on.

Print extent: default is full screen.

Printer form-feed: default is off.

Graphics mode: default is off.

AccuTerm VT220, VT320 and VT420 emulations support 5 character sets: ASCII, Multinational, ISO-

Latin1, Graphics and Scientific. The default character set assignment is G0=ASCII, G1=ASCII,

G2=Multinational and G3=ASCII. The GL set (hex 20-7E) defaults to G0 (ASCII) and the GR set (hex

242 AccuTerm 7 Help

A0-FE) defaults to G2 (Multinational).

The key to be programmed is specified by

In addition, the VT420 emulation has user-definable macros. Use the following command to define macros.

DCS

id ; dt ; fn ; en ! z value

Id is a macro identifier, which must be in the range of 0 to 63. If dt is 1, then all current macros are deleted before the new macro is defined. en specifies the encoding: 0 for ASCII text, 1 for hexadecimal. Value is the macro contents in the specified encoding format.

Invoking a macro has the same effect as if the terminal had received the macro contents from the host.

The following command may be use to invoke a defined macro:

id * z
